I, Grand Commander of the Imperial Guard, You Call Me the Discarded Heir

Lin Fan transmigrates as an unfavored heir in a princely mansion, where he is framed by Princess Consort Qin Hui and his younger brother Lin Xiaolong, forcing him to flee. With the help of maid Qing Luo, he breaks through to become a martial artist, kills the pursuing soldiers, and escapes under the protection of the Imperial Guard. While serving in Ping'an County, he encounters Zhao Cheng colluding with bandits, defeats them with gunpowder, earns merit, and rises in rank. Upon entering the capital, he is tasked with finding the Nine Dragon Jade Disc. During the journey, he is ambushed; Qing Luo falls off a cliff, but Lin Fan explodes in rage, breaks through, and kills her attackers. In the Northern Liang region, Lin Fan captures Princess Mingyue and obtains the Jade Disc. He mistakenly reports Lin Xiaolong's name, which wins the princess's heart. Upon returning to the capital, the princess shields him from an arrow. Qing Luo leads the Tai Xuan Palace forces to capture Lin Xiaolong, brings Qin Hui and others to justice, and Lin Fan begins his harem war with his three wives.
